Up to 10 medical workers were injured, six of them seriously, when a crowd of grieving relatives armed with knives stormed a major Shanghai hospital on Monday.
At one point, the crowd attempted to throw a doctor out a window.
Authorities detained six people in relation to the incident, allegedly sparked by a dispute over the treatment of an elderly male patient before his death.
Although the incident occurred on Monday morning, it was not reported by Shanghai media until yesterday afternoon.
A municipal government spokesman said he had nothing to add to a brief press release on the city's official news portal, eastday.com.
A spokesman at Xinhua Hospital - in the city's northeastern district of Hongkou and affiliated with the Shanghai Jiao Tong University Medical Department - also declined to comment.
According to reports, a group of between 20 and 30 mourners gathered outside the entrance to the hospital's casualty department at around 8am. They set up a funeral altar for Liu Yonghua and unfurled banners.
